Now many people had this need that they wanted to log in to their one WhatsApp account in their multiple devices so that they could get all the chats and files etc. of the same WhatsApp account. But at that time, WhatsApp There was a limitation that if you wanted to use more than one WhatsApp account, you had to register with a separate number, but WhatsApp has removed this limitation and added a new feature called Companion Device to WhatsApp, which makes the life of WhatsApp users a lot easier because by using this feature of WhatsApp, you can access and use your WhatsApp account on multiple devices and use this WhatsApp account freely.

What is WhatsApp Companion Device feature
Now let’s first see what WhatsApp Companion Device means. Now WhatsApp has added a new feature by which you can use the same WhatsApp account on multiple devices without having to put a separate SIM number on each device or without registering with a new number. Now WhatsApp has officially launched this feature in its WhatsApp application and also promotes this feature as WhatsApp Link Device.
Example
If I give you an example of this, WhatsApp’s Companion Device feature works in such a situation that you have a primary phone where your WhatsApp SIM number is only registered and that is your primary device. Now you have a laptop or another mobile on which you want to register the same WhatsApp account, but you also want that WhatsApp is not logged out in your primary phone, then you can use this feature and open this WhatsApp on your laptop and mobile at the same time. You can also use it and apart from that, your WhatsApp app which is on your primary mobile will also not be logged out.
What is WhatsApp Web and its limitations
Now if I talk about WhatsApp Web, it also worked in the same way but it had many limitations. WhatsApp Web was available only for laptop or PC users for WhatsApp users. But there was a disadvantage in this too that as soon as the internet was disconnected from the mobile, WhatsApp Web stopped working. All the data depended on the phone. But after 2023, WhatsApp produced multi-device 2.2 in which they enabled end-to-end encryption and chatting without a phone and made independent device login possible. Now, by 2026, WhatsApp has made this feature so stable and fast that now, through this feature, you can access and use your primary WhatsApp account on multiple devices and it is also very secure. We will talk about its security in the next headings.
How to use WhatsApp Web if Primary Mobile is Not in Range
How can you access WhatsApp Web without your primary phone? If you do not have your primary phone with you or it is very far away from you, then you have to open WhatsApp Web in your Chrome browser. There you will find an option Link Device with Phone Number. You have to click on it. Now there you have to add the mobile number which is the WhatsApp number of your primary phone. As you add it, a code will be generated in front of you. After copying this code, you have to go to WhatsApp on your primary mobile and paste it in the Link Device option. Then your WhatsApp will open in your Chrome browser. Even if you do not have your primary mobile, this is a feature. But by using this feature, you can open WhatsApp on your mobile as WhatsApp Web in multiple devices, but still, you will have to give access from your primary mobile.
